AI Voice Agents - The Complete Guide to Voice Chat (2025)
Learn everything about an AI voice agents, its benefits, implementation tips, and the AI voice chat applications for business success.
Longer wait times, high call volumes, and language barriers in call centers often frustrate customers. Complex interactive voice response (IVR) menus only add to the problem, leading to customer dissatisfaction. That’s why companies are adopting smarter self-service solutions like artificial intelligence (AI) voice agents. In fact, experts predict the voice bot market will reach $98.2 billion by 2027, showing a clear trend toward smarter solutions to improving customer experience.
AI voice agents technology combines Natural Language Processing (NLP), machine learning, and voice recognition to transform customer interactions. It provides quicker, more efficient service and improves the overall customer experience.
In this guide, we'll explore what AI voice agents are, their key features, practical use cases, and tips on how to implement a voice agent in your business.
What is an AI voice agent?
An AI voice agent is a two-way conversational tool that communicates with the customer. It automates inbound and outbound calls without human intervention and transfers calls to a human agent when needed.

The biggest advantage? Callers can navigate an IVR by speaking naturally, without listening to long, complex menus or pressing numbers on a keypad.
Popular AI voice agent examples include Apple's Siri, Google Assistant, and Amazon's Alexa. These tools simplify interactions, provide instant answers, and automate tasks. In contrast, advanced bots like IBM’s Watson Assistant and Microsoft’s Cortana handle customer support, sales inquiries, and internal communications.
Types of AI voice agents
Here’s a breakdown of the four main types of AI voice agents and how they can benefit your business:
Rule-based AI voice agent
Rule-based voice agent use predefined sets of questions and rules to offer answers or perform tasks. Such voice agents handle routine tasks and customer FAQs. They answer all queries that fall under the if-this-then-that logic.
For example, an e-commerce site using a bot to guide customers in checking their order status or a banking site handling routine inquiries like balance checks, bill payments, transaction histories, etc.
AI-assisted voice agent
AI-assisted voice agents use machine learning and natural language to interpret conversations so they can analyze the context and grasp what the speaker means. This makes them far more capable and user-friendly than the conventional, rule-based voice agents.
Let’s suppose a user asks Alexa, 'What's the weather tomorrow?' and then follows up with, 'How about next week?' it remembers the context. This adaptability means customers don’t have to repeat themselves, creating a more contextual customer experience.
Conversational AI voice agent
Conversational voice agents make conversations using natural language. They’re more nuanced than AI-assisted voice agents as they can handle complex conversations using everyday language to create more personalized interactions.

Google Duplex, and IBM Watson Assistant, are examples of conversational voice agents. They can make phone calls, make reservations, and handle natural conversations with a human-like tone.
Voice-activated voice agent
These bots use voice commands to answer practical questions and perform routine tasks. They are more flexible than personal voice agents that adapt to speakers and perform customized tasks.
Such bots serve as digital assistants to AI-assisted bots like Siri.
How does an AI voice agent improve customer engagement?
A customer calling your sales team wants to feel valued and understood. An AI voice agent does that. It puts the customer at the center, creating a better experience and driving business benefits as a result. Let’s understand it with a few use cases.
Use case: Get a quick update on order status, 24/7

Assuming the AI voice agent is integrated into your CRM, it greets the customer by name. Instead of navigating through a branched IVR to get their order status, the customer can simply say ‘order status’ and the voice bot pulls out the order details from the CRM and gives the user a real-time update within seconds.
Sheraz Ali, the Founder of HARO Links Builder states that their voice agent managed over 30% of customer interactions in one of their company projects and drastically reduced wait times.
“It also improved our response efficiency and led to a 20% increase in customer satisfaction scores and a reduction in operational costs within three months.”
Benefits:
- Decreased waiting time.
- Limited IVR menu navigation.
- No human intervention is required.
- Quick response times.
- Reduced business costs.
- Tangible increase in customer satisfaction.
Use case: Improve language learning for students

A language learning platform uses a voice agent to provide real-time translations and personalized tutoring. So the voice agent instantly supports students in any subject by translating and clarifying complex terms in their preferred language.
Benefits:
- Reduced requirement for multilingual staff.
- Increases inclusivity as the bot answers in the user’s preferred language.
- Language barriers are removed.
Use case: Improve patient outcomes in healthcare

It's easy to miss appointments or forget to deliver prescriptions to the patient’s home timely. A healthcare service can employ a voice agent to deliver personalized care and offer preliminary health assessments, medication reminders, and easy appointment scheduling, all according to the individual patient's needs.
Benefits:
- Saves time by streamlining appointment bookings.
- Ensures medication adherence with timely reminders.
- Reduces workload for healthcare providers with automated support.
Use case: Streamline routine financial services

Once integrated with the banking system, the voice agent automates routine financial tasks, provides instant account information, processes transactions, and delivers personalized financial advice around the clock.
Benefits:
- 24/7 access to financial services without wait times.
- Improves customer experience with quick, accurate responses.
- Automates routine tasks, freeing up staff for complex queries.
- Provides personalized advice to improve financial decision-making.
Use case: Get personal shopping assistance

An e-commerce platform can use a voice agent to assist customers with product selection, provide personalized recommendations, and automate the sales process from start to finish.
Benefits:
- Delivers a personalized shopping experience 24/7.
- Boosts sales with customized recommendations.
- Reduces cart abandonment by guiding customers to checkout.
- Improves customer satisfaction with fast, accurate service.
Features of an AI voice agent
To understand why voice agents are so effective, let’s look at the key features that improve the overall customer service experience while streamlining business operations.
The best voice agents for businesses come equipped with:
Natural language understanding (NLU)
An AI voice agent understands user queries by converting speech into text using AI and NLP. It then forms an appropriate response and converts it back into speech using text-to-speech (TTS) technology. This ability to understand and respond in natural, conversational language sets AI voice agents apart from traditional IVR systems, which rely on rigid, menu-based responses.

Personalization capabilities
Customers want quick, personalized responses to their queries, unlike complex IVR systems that frustrate them with lengthy menus. An AI voice agent offers contextual conversations, adapting to the user’s intent. It detects speech cues, skips irrelevant interactions, and also transfers calls to the right agent.
Hence, when comparing voice agents to IVRs, the bot's ability to offer personalized interactions like a human outshines communication systems that follow even the best IVR practices.
Multi-language support
AI voice agents break down language barriers, supporting multiple languages to provide a more inclusive and accessible customer experience. Businesses can easily connect with diverse customer bases across the globe.
For instance, Plivo supports speech recognition in 27 languages and their regional variants.

Integration with other platforms and services
AI voice agents easily integrate with platforms like customer relationship management (CRM) systems, Enterprise resource planning (ERP) tools, and ticketing software. They access and update customer data in real time to ensure accuracy.
These bots also pull relevant details, automate follow-up actions, and sync with communication channels like email or chat. This creates a personalized and consistent customer experience across all touchpoints.
Benefits of voice agents
Let’s now look at the benefits of AI voice agents.
Enhanced user experience
Many businesses have concerns over the quality of a voice agent for customer service. However, a voice agent answers queries quickly regardless of the time of the day. Speedy, reliable answers are important to providing excellent service, making voice agents an invaluable tool for businesses looking to improve customer satisfaction.
Additionally, businesses can:
- Handle routine queries and common tasks faster than human agents.
- Remove the need for users to navigate complex IVR menus.
- Manage high-volume calls without errors.
Better cost efficiency
An AI voice agent doesn’t just save time, it also saves money. It boosts user satisfaction and reduces support times by automating repetitive queries. This frees up staff for higher-value tasks, and interacting with customers after hours has improved lead conversion.
The direct benefits to businesses are:
- Reduces the need for a larger customer support team.
- Allows human agents to focus on complex, high-value inquiries.
- Engages users outside business hours to boost marketing return on investment (ROI).
- Lowers training costs and minimizes the risk of providing incorrect information.
Accessibility for users with disabilities
With over one billion people living with disabilities worldwide, voice agents make services more inclusive. They enable hands-free, accessible interactions, allowing customers with visual, motor, or cognitive impairments to engage with the business easily. This not only improves customer satisfaction but also broadens the company’s reach to a more diverse audience.
Data collection and analysis for improved services
Voice agents don’t just serve customers — they also gather insights. Use this data to analyze data and improve services, personalize marketing efforts, and make more informed business decisions.
24/7 availability
Unlike human agents, voice agents are always accessible. They ensure customers get help whenever they need it, contributing to a more consistent and reliable customer experience.
Future of AI voice technology
As IBM's data engineer, Chris Hay puts it, "We're entering an era where every mom-and-pop shop can have the same level of customer service as an enterprise." This statement captures the transformative potential of voice recognition technology.
AI voice chat applications benefit businesses of all sizes by delivering top-tier customer experiences. Tech giants are already paving the way. Microsoft has updated its Copilot AI with advanced voice capabilities, allowing it to handle complex queries with natural language reasoning, while Meta has introduced voice AI to its messaging apps.
AI voice assistants will move beyond smartphones, integrating into wearable devices like the recently unveiled Meta Orion augmented reality glasses. For businesses handling sensitive client relationships, this could mean smarter, empathetic bots that mirror the tone and approach of a human assistant.
Key upcoming trends:
- Hyper-personalization: Customized voices and targeted recommendations.
- Advanced problem-solving: Managing complex queries using natural language.
- Real-time analytics: Analyzing customer tone for deeper insights.
Yet, challenges remain. Arvind Rongala, the founder of a skill-management solution provider, shares, “There are still issues, especially with data privacy and ensuring interactions are human-like. In addition to resolving problems with bias in training data and regulatory compliance, businesses must strike a balance between automation and personalization. For example, adhering to GDPR regarding the storage of voice data can be challenging, but doing so is essential to fostering trust.”
Ultimately, businesses need to prioritize data security, explore multi-device integration options, and develop stronger contextual understanding for natural interactions.

RCS Marketing 101: Your Complete Guide
Discover how RCS marketing delivers rich, branded messages that drive engagement for your business.
SMS marketing works, but let’s be honest: it feels a bit outdated compared to modern apps.
But what if you could send rich, interactive messages with branded content, images, buttons, and carousels straight to your customers’ native messaging apps?
Rich communication services (RCS) makes that possible.
If you’re ready to explore how RCS marketing can transform your engagement strategy, this guide will walk you through everything you need to know. Let’s get started.
What is RCS marketing?
RCS marketing uses rich communication services to send interactive, branded messages through a customer’s default messaging app. It’s a modern upgrade to SMS that lets businesses share images, buttons, carousels, and more — all without needing third-party apps.
A user on Reddit summed up this perfectly:

RCS lets you send messages that are visually branded with logos and colors while remaining interactive. This turns static updates into an app-like experience inside a message.
This shift is part of a broader industry move, led by Google and backed by major mobile carriers, to upgrade messaging infrastructure and make RCS the default standard on Android devices.
As support continues to grow, businesses are adopting RCS as part of their customer engagement strategy. Platforms like Plivo make that adoption easier with a reliable, enterprise-grade gateway to deliver rich, reliable RCS campaigns at scale.
RCS vs. SMS marketing: A quick comparison
Marketers today are looking for ways to deliver more interactive and visual communication, and RCS is clearly leading the way.
While SMS still works well for simple alerts, it lacks the creativity and engagement that RCS marketing offers.
Let’s take a quick look at RCS vs. SMS marketing.
4 key benefits of RCS marketing
RCS marketing makes messaging feel more natural for both you and your customers. And since you can see what’s working and what’s not, it’s easier to pivot your strategy and get better results.
Here are its four key benefits.
1. Improved user interaction
One of the biggest advantages of RCS marketing is how seamless it makes the experience for your customers. Instead of typing out replies or clicking a link to open a website, users can just tap a button right inside the message.
Want them to book a demo, check order status, or browse products? It’s all possible with just a tap.
Fewer steps mean less effort, and that leads to more people following through. In fact, individuals spend up to 37 seconds engaging with RCS messages, which is a lot longer than most other types of mobile messaging.

That extra time and interaction can make all the difference when you’re trying to convert interest into action.
2. Consistent brand experience
RCS marketing doesn’t just tell people who you are — it shows them.
Verified business profiles help people know they’re getting messages from the real brand. Every message shows your brand’s logo, name, colors, and a checkmark. These small details make it clear that the message is coming from a genuine source.

This consistency matters because 88% of people are more likely to buy from a brand they trust.
3. In-depth analytics
With RCS marketing, you can track open rates, button clicks, and how people interact with each part of your message.
You get clear visibility into what’s working and where users are dropping off.
This makes it much easier to measure the return on investment (ROI) and fine-tune your campaigns. The more you understand how people engage, the better you can shape your messaging for results.
4. Higher conversion potential
RCS marketing makes it easier for customers to take action — whether that’s browsing products, booking a service, or making a purchase — all within the message itself.
With fewer clicks and no need to switch apps, the path to conversion feels effortless. And when it’s that easy, more people follow through.
For example, EaseMyTrip used RCS to run a post-COVID travel survey. They added quick-tap answer options and followed up with a thank-you coupon. The campaign saw a 4x higher click-through rate than email, 10x more survey completions, and a 2.7% increase in conversion rate.
5 major use cases of RCS marketing
Here are five major use cases showing how brands are using RCS marketing effectively.
1. Product promotions
RCS makes product promotions feel more like browsing a store than reading a message. Brands can send image carousels that customers can swipe through to explore new arrivals, check product details, and see what’s available without leaving their messaging app.

2. Abandoned cart reminders
The average cart abandonment rate is over 70%, which means most shoppers never make it to the finish line. RCS marketing can help bring them back by making the reminder more engaging and easier to act on.
You can send a message that shows exactly what they left behind, along with a clear button to complete the purchase. It’s visual, straightforward, and the entire experience stays within their messaging app.
3. Appointment confirmations and reminders
A PhD thesis from Manchester Metropolitan University found that forgetfulness is the most common reason people skip their appointments.
RCS makes it easier for both businesses and customers to stay on the same page. You can send a message that shows the appointment details along with a simple calendar view. Add buttons to confirm, reschedule, or cancel — all within the chat.

4. Customer surveys and feedback
Getting feedback is important, but most customers lack the time or patience to complete lengthy forms. RCS marketing makes it easier by allowing brands to ask short, targeted questions and receive quick responses.
Plus, the rich features of RCS let you include images, ratings, or multiple-choice options, making feedback feel more like a conversation.
5. Customer support follow-ups
After a support request is resolved, following up shows customers you care and helps close the loop on their experience. But if the follow-up message gets buried in an email inbox or goes unnoticed, that opportunity to connect is lost.
With RCS marketing, you can send a quick message to check if everything’s working fine. You can include helpful buttons like “Change Password,” “Manage Account,” or “Talk to Support.”

RCS marketing myths and realities
Despite RCS marketing’s growing adoption and proven results, some common misconceptions still hold businesses back from trying it. Let’s look at a few of the biggest myths and what’s actually true.
Myth 1: RCS marketing is too expensive
At first glance, RCS business messaging can seem like a pricey upgrade. Rich visuals, tap-to-action buttons, and branded layouts look premium, so it’s easy to assume they come with a hefty cost.
But cost alone doesn’t tell the full story.
What you get in return matters more. RCS drives significantly stronger engagement with higher click-through rates, increased interactions, and better overall outcomes.
Take Club Comex, the loyalty program of North American paint brand Comex. They sent two rich and interactive RCS campaigns to their members and saw a 10x higher click-through rate, which helped increase revenue by 115%.
That’s the value side of the equation. Better targeting and richer content mean more people click, engage, and convert.
Myth 2: RCS marketing doesn’t reach enough users to be worth it
This concern made sense in the early days of RCS, when adoption was still catching up. But the landscape looks very different now.
In June 2024, the 12-month growth of RCS users reached 36.3%, showing faster uptake than other messaging channels. More Android devices support RCS by default, and it’s being rolled out across more networks globally. Even Apple has announced support, which means RCS is on track to reach a massive number of smartphone users worldwide.
With that kind of growth and widespread support, the hesitation around RCS is starting to fade. Brands can confidently invest in RCS marketing knowing it will connect with more customers than ever before.
Myth 3: RCS gets treated like spam and ends up ignored just like emails
Unlike email, RCS messages appear directly in the user’s primary messaging app alongside personal conversations. They include rich media and interactive elements, making them more engaging and less likely to be ignored.
This creates a more natural, conversational experience that drives higher open and response rates than traditional marketing channels.

If you’re still relying on manual replies, scripted chatbots, or email follow-ups, you’re leaving response time and revenue on the table.
The smarter path? AI-powered WhatsApp agents. They’re full-service, no-code agents that can resolve issues, qualify leads, and send personalized offers 24/7.
In this guide, we’ll walk you through WhatsApp agent setup using Plivo and understand how these agents help you automate conversations that convert.
What is a WhatsApp AI agent?
A WhatsApp AI agent is an automation designed to operate over the WhatsApp Business API. Unlike scripted bots, agents are built to understand intent, pull in context from your internal systems, and complete business tasks like answering account-specific questions or initiating transactions.
Plivo’s WhatsApp AI agents can be trained to use your brand voice, integrated with your CRM or helpdesk, and customized to handle specific use cases, such as subscription renewals, cart recovery, refund processing, or customer onboarding.
They are accessible through a no-code interface and support a multilingual, omnichannel customer experience across WhatsApp, SMS, RCS, and voice.
What you need before setting up your agent
To go live with a WhatsApp agent, you need:
- A verified Meta Business Account
- An active WhatsApp Business Account (WABA) tied to a phone number
- Pre-approved message templates for outbound communication
- WhatsApp Business API access through a business solution provider (BSP) (Plivo offers this natively)
- A platform to design, train, and manage agents (Plivo Agent Studio)

Optional but recommended integrations:
- CRM (like Salesforce, HubSpot, or Zoho)
- Helpdesk (like Zendesk or Freshdesk)
- E-commerce or billing tools (Shopify, Stripe, etc.)
Step-by-step: How to set up a WhatsApp agent with Plivo
Follow this step-by-step guide for a smooth WhatsApp agent setup with Plivo.
Step #1: Choose your primary use case and define agent scope
Don’t build a generic bot. Start with why you’re automating. This could be handling support queries, sending order updates, re-engaging inactive customers, or managing subscription renewals.

Plivo provides a library of prebuilt AI agents for common use cases like cart recovery, lead qualification, appointment reminders, and product recommendations. You can choose to use one as-is or customize it to fit your business process. Each agent is compatible with WhatsApp and designed to operate across channels as needed.
Step #2: Build the agent using Plivo’s no-code platform
Since your API access is already set up, you can begin building your agent in Plivo’s Agent Studio. This is a visual, drag-and-drop builder where you create conversation flows using blocks that represent actions, responses, conditions, and triggers.

You can structure your flow to respond to specific keywords, match customer intent, route inquiries to different departments, or escalate to a live agent when needed. Each step in the journey can include media-rich responses like buttons, product carousels, quick replies, and file attachments.
Beyond logic design, you can also configure fallback rules for when the agent is unsure, and add human handoff conditions to ensure escalations happen smoothly with full context transferred to the live agent.

This step allows you to fully customize the agent’s tone, workflow, and logic to reflect how your brand communicates.4
Step #3: Train your agent with AI
Plivo supports integration with internal systems like your CRM, order management platform, inventory tools, or helpdesk. This means your agent can access real-time customer data, past orders, preferences, and policies to deliver personalized responses.
You can also connect your knowledge base, including FAQs, SOPs, product documentation, or policy articles. These resources train the agent to respond accurately and contextually, without needing scripted answers.

For natural language understanding, Plivo gives you the flexibility to choose the AI model that powers your agent.

Step #4: Test, launch, and monitor your agent
Once your flow is built and trained, run controlled tests:
- Check for flow accuracy and intent matching
- Review how it handles incomplete or unclear inputs
- Test human handoff and see if the agent transfers the full context

Plivo’s real-time dashboard lets you:
- Monitor delivery, engagement, and satisfaction metrics
- Track where users drop off in conversations
- Identify areas to improve agent logic or content
- Compare campaign and agent performance across channels
After launch, your agent keeps learning. As more customers interact, you’ll gather insight to improve how it responds or what paths it offers.

Key benefits of WhatsApp automation
By automating routine tasks, WhatsApp can help your business stay responsive and consistent across customer touchpoints. Here’s how it can benefit your business:
Reduce manual workloads and response times
When you automate WhatsApp interactions, every department, from marketing to customer service, runs more smoothly.
By automating routine tasks like order updates, FAQs, and customer inquiries, businesses can significantly reduce the manual effort required.
This means your team spends less time on repetitive tasks and more time focusing on high-priority interactions.
Increases the scalability of customer interactions
As your business grows, the number of customer interactions increases. Automation allows you to scale communication efforts without hiring additional staff or losing the personal touch.
Whether you're dealing with 50 or 5,000 customers, automated responses ensure that each inquiry is handled swiftly and consistently.
Enhances customer experience through personalization
Automated WhatsApp messages can be personalized based on customer data, creating a more relevant and tailored experience.
From addressing customers by name to offering product recommendations based on past purchases, personalization makes customers feel valued. This leads to higher engagement rates and improved loyalty.
Cost-effectiveness compared to manual processes
WhatsApp automation eliminates the need for large customer support teams and reduces the time spent on repetitive tasks.
This saves on operational costs and also leads to a more efficient allocation of resources.
5 popular use cases of WhatsApp automation across industries
Businesses everywhere are finding new ways to use WhatsApp automation. Here are five popular examples:
1. Customer support
Automating common FAQs and routine inquiries on WhatsApp helps customers get instant answers anytime. This reduces the number of tickets support teams have to handle, letting them focus on more complex problems.
2. E-commerce operations
Order confirmations, shipping updates, and delivery notifications keep customers informed every step of the way. Automating returns and collecting feedback via WhatsApp speeds up these processes and improves customer satisfaction.
3.Marketing and lead nurturing
Automated lead follow-ups ensure timely, consistent engagement with prospects, boosting conversion chances. Also, you can use personalized re-engagement campaigns to help bring back inactive customers with offers or updates tailored to their interests.
4.Event management and invitations
Automated WhatsApp invites, updates, and follow-ups keep your audience informed and engaged, boosting the attendance rate. This helps you stay connected and make every event a success.
5.Appointment scheduling and reminders
Timely reminders help customers remember appointments, reducing cancellations and improving the overall experience. Automation makes scheduling easier and more efficient for both businesses and customers.
Step-by-step guide to implement WhatsApp automation for your business
To successfully implement WhatsApp automation, follow these key steps that cover planning, setup, and optimization.
Step 1: Define your use cases and goals
Start by identifying which business functions, such as order updates, customer support, or lead follow-ups, will benefit most from automation.
Set clear, measurable goals like:
- Reducing response times
- Lowering manual workload
- Boosting customer engagement
This will guide your automation strategy and help you track success.
Also, ensure compliance from the start. WhatsApp requires businesses to obtain explicit customer opt-in before sending messages. To stay compliant:
- Use clear, transparent language when requesting consent.
- Collect opt-ins through channels like website forms, checkout flows, or click-to-chat ads.
- Log and manage consent within your systems for audit readiness.
Data privacy and compliance are essential for building trust and maintaining long-term customer relationships.
Step 2: Choose the right WhatsApp business API provider
Select a platform that fits your specific needs. Look for features like:
- Robust CRM integrations
- Audience segmentation
- Flexible automation workflows
These capabilities simplify your communication and scale your efforts efficiently.
Make segmentation a priority, use tagging and grouping strategies to target the right customers with the right messages.
With smart tagging and grouping, you can:
- Deliver personalized messages
- Engage the right people at the right time
- Improve conversion and retention
Step 3: Set up your WhatsApp business account
You must set up a verified WhatsApp Business account to use WhatsApp for automated messaging. This includes:
- Registering your business name and details.
- Verifying a dedicated phone number.
- Getting approval from Meta to use the WhatsApp Business API.
This ensures that your business is recognized as a legitimate sender.
Your WhatsApp API provider will typically assist with onboarding, including submitting documentation and setting up the technical aspects.
Some platforms also offer pre-built tools to help you manage mobile number registration, display name approval, and message template submissions.
Step 4: Create and submit message templates
Start by designing message templates for everyday customer interactions, such as:
- Promotional messages (e.g., limited-time offers)
- Transactional updates (e.g., order confirmations, delivery alerts)
- Support messages (e.g., ticket updates or issue resolution)
Each template must follow WhatsApp’s formatting and content policies.
Once your templates are ready, submit them through your WhatsApp API provider for Meta’s approval. Only approved templates can be used for proactive messaging.
Step 5: Build automation workflows
Now that your account and templates are ready, it’s time to connect WhatsApp with the rest of your tech stack. Integrate with:
- CRM systems (to access customer data)
- Support tools (for query management)
- E-commerce platforms (to track orders and actions)
Use event-based triggers, like a new order, a cart abandonment, or a support ticket, to automatically send relevant messages.
Additionally, plan for human fallback. Automation can’t handle everything. Build intelligent workflows that escalate to a human agent when:
- A customer requests help
- The query is too complex
- Sentiment detection flags a negative experience
This keeps your support experience smooth, responsive, and frustration-free.
Step 6: Test, launch, and optimize
Start with a pilot campaign to ensure everything runs smoothly.
Track key metrics:
- Response time
- Open rate
- Conversion rate
Use these insights to refine your workflows, improve message content, and adjust targeting.
Best practices for WhatsApp automation
Following some proven best practices is essential to get the most out of WhatsApp automation. Here’s what you need to know:
Tips for optimizing messaging frequency and timing
To keep your audience interested, it's vital to message thoughtfully and strategically. Here are some quick tips:
- Avoid over-messaging to prevent unsubscribes.
- Use analytics to identify when your audience is most active and receptive.
- Space out messages to keep it natural.
- Monitor response rates and adjust based on customer behavior and feedback.
Leverage data analytics for campaign performance
By tracking metrics such as open rates, click-through rates, and response times, you gain valuable insights into what works and what doesn’t. Use this data to refine your messaging, target relevant audience segments, and optimize timing.
Regularly reviewing analytics helps you make informed decisions that boost engagement and drive better results over time.
Compliance and customer privacy protection
To protect your customers and stay compliant, focus on these key areas:

One place to manage every interaction—Plivo’s commitment to the unified Contact Center
Implementing a Contact Center that unifies the agent workflow and simplifies operations is essential to exceeding the needs of the intelligent consumer.
The business-critical role assumed by Contact Centers has been driven by mounting customer expectations and requires more personalized touchpoints and faster issue resolution.
Consumers and the technologies they use are increasingly intelligent and require smarter solutions as we enter the next chapter of the unified Contact Center.
In the past couple of years, businesses have adopted modules from legacy vendors that promised features like AI, automations, self service, and native analytics within their existing solutions. They thought they were purchasing the future, only to realize three things:
- Simplicity and flexibility are key with customer experience technology. Plugging in a module doesn’t necessarily equate to a personalized customer experience.
- Contextual agent experience is more important than ever to build customer loyalty.
- Voice as a channel contains incremental costs across every CCaaS provider; it adds up quickly, and it doesn’t have to.
While the Contact Center space is approaching maturity, it won’t truly arrive until we accept as an industry certain methodologies and tech prerequisites for the platforms that power the customer service experience.
- Contact Center software must serve as the primary hub of a modern CX tech stack.
- Contact Center software needs to provide an intuitive experience for agents and an invisible experience for customers.
- A single platform that can adapt and be customized is essential. Non-customizable tools with certain non-native features are a non-starter.
Verticalization of the Contact Center
Mid-year 2021, communications API industry veteran Plivo launched a powerful yet simple Contact Center platform—with fully native communication channels and analytics—to address the maturity gaps in an established and fast-evolving space. Plivo’s engineering team built a unified platform to manage the entire CX workflow, optimized the add-on costs of voice communications, and integrated it with the other complementary CX tools in your existing tech stack, all powered by Plivo’s communications API platform.
The result is Contacto, a fully native platform that integrates with tools like Salesforce, Shopify, Zendesk, Kustomer, Servicenow, and more. Contacto was architected to drive customer loyalty and reduce complexity, while ensuring that agents have a simple and seamless experience with their workflows. With common pain points in the customer experience as its focal point, Contacto was built to level up CCaaS technology using real-world CX gaps as the North Star. These include:
- Customer experience, on their terms: Meet your customers on the channels and devices they demand.
- Unified agent desktop experience: One platform manages all interactions with continual context available so your customers don’t have to repeat themselves—ever.
- Simple configuration and drag-and-drop workflow builder: Build powerful no-code workflows that keep your agents moving forward and your customers happy.
Contacto, Powered by Plivo
The Contacto Contact Center experience is the next chapter in Plivo’s rich history. Contacto is built on Plivo’s Premium Communications Platform, which has been proven for scale over the last 10 years with billions of API requests each month. It natively supports voice and emerging channels like in-app chat, WhatsApp, and social media and has prebuilt integrations with existing applications like Salesforce, Zendesk, Shopify, Kustomer, and more.
We are glad to be here, and we can’t wait to bring the Contact Center space to maturity with the help of our amazing customers and our strong foundation in scaling the Plivo API platform globally in 190+ countries.

How retail and e-commerce brands can take a cue from healthcare customer service
Contact Centers in the healthcare industry offer ample learning opportunities to B2C brands looking to optimize their operation.
Unlock new potential in your contact center by implementing these healthcare customer service secrets.
In the healthcare industry, contact centers are generally more established and mature with efficient routing, tried and true metrics, and continuous quality improvement. Early stage or B2C companies in the retail, ecommerce, regional utility, and non-profit sectors can learn and apply valuable lessons to their (perhaps) less-complex support operations. Granted, the healthcare industry as a whole has a long way to go in leveraging data to eliminate friction and elevate the customer-patient experience, but recent changes to the trajectory of the industry as a whole can inform more nimble contact centers how to offer best-in-class customer interactions.
The notion of the “longitudinal health (or human) record” is one on which even the US government has provided input and guidance to the healthcare industry in efforts to drive improved health outcomes. The basic idea is that all medical providers have access to your single, master copy, digital patient record so as to coordinate, de-duplicate, and improve care delivery. As you consider how to deliver a fast, frictionless experience in your B2C contact center, consider how looking at your customers through the lens of a longitudinal engagement record can inform your contact center priorities:
- Know Me - Customers expect you - to a reasonable degree - to know who they are and their history with your brand. What are the vitals or key data points your agents need to know about your customers? Contacto’s integrations with industry-standard CRMs and OMSs offers your agents a seamless view into previous customer interactions with the Customer Data and Customer History panels.
- Help Me - Customers want to be delighted. Contacto eliminates the “swivel chair” system hopping and operational redundancies by empowering your agents with data, context, and line of sight via a single-pane-of-glass workbench so they can go the extra mile with proactive, human-centric service. Kinda like NOT being handed a clipboard at the doctor’s office. One can dream!
- Keep Me - Customers will come back. If you’ve treated them with dignity and eliminated friction — armed with context, your most valuable asset — transactional and relational scores will be primary symptoms to the underlying dividends yielded in customer loyalty and lifetime value.

How to Send MMS in Java using Plivo's Messaging API
Plivo's SMS API and Voice API enables businesses to communicate with their customers at global scale. Sign up for free now.
You can send an MMS message to any phone number. Businesses can make messages more meaningful by using MMS instead of SMS and including images, audio, and video to provide context. Here’s how to use Plivo’s SMS APIs to send outbound MMS text messages.
How it works

Prerequisites
To get started, you need a Plivo account — sign up with your work email address if you don’t have one already. If this is your first time using Plivo APIs, follow our instructions to set up a Java development environment.
Create the send MMS application
Once you have the above prerequisites set, You can follow the below instructions to create an app to send an outbound MMS to deliver your message.
Create a Java class called SendMMS and paste into it this code.
Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, +12025551234). In countries other than the US and Canada you can use a sender ID for the message source. You must have a Plivo phone number to send messages to the US or Canada; you can buy a Plivo number from Phone Numbers > Buy Numbers on the Plivo console or via the Numbers API.
Note: We recommend that you store your credentials in the auth_id and auth_token environment variables to avoid the possibility of accidentally committing them to source control. If you do this, you can initialize the client with no arguments and Plivo will automatically fetch the values from the environment variables. You can use System.getenv() to store and retrieve environment variables when initializing the client.
Test
Save the file and run it.
Note: If you’re using a Plivo Trial account, you can make calls only to phone numbers that have been verified with Plivo. You can verify (sandbox) a number by going to the console’s Phone Numbers > Sandbox Numbers page.

Transforming the Contact Center from a reactive resolution dinosaur to business-critical growth driver
Transform your Contact Center from a reactive resolution dinosaur to a healthy, business-critical growth driver with these four steps.
Since the inception of the Contact Center more than 60 years ago, the demands placed on it by the business have increased every year. This increase is primarily due to the sheer volume of consumer products and services paired with the rise of communication technology. In response to this relentless pressure, new features were tacked on over time, morphing the Contact Center into a clunky but immeasurably necessary business unit. And more recently, it has been acknowledged as a critical revenue center.
We’re at a pivotal point in the life cycle of the modern Contact Center for two primary reasons:
- The demands on Contact Centers will only continue to increase as technology advances and consumer communication preferences shift. The rapid pace of growth makes it difficult to know what the business needs are for today and will be for the future.
- Contact Center vendors may offer similar features on paper, but these features were often created agnostic of the others and lack the required interoperability. And each new technology added seems to create exponential growth in complexity.
The result of the two points above? A reactive customer service motion that is, simply put, stuck between having too many tools (not having a single reliable place to manage every interaction) and having a piecemeal data/reporting strategy that makes optimization decisions difficult.
The road to implementing a healthy Contact Center - getting started
We know that unnecessary complexity is detrimental, but doing nothing in the face of shifting consumer trends is perhaps moreso. So how do we plot a course forward that both keeps up with consumer trends and fits your business? We’ve come up with a list of considerations that will take your CCaaS operations from large, clunky dinosaur status to living, breathing, revenue-driving workflows that blend CC philosophy with technology.
- Identify the objectives of your Contact Center
By understanding the SMART goals of a Contact Center, your organization will be able to home in on what truly matters as it relates to processes and technologies. These objectives might include CSAT, customer retention rate, time to resolution, NPS score, repeat customer tickets, similar issues, etc. - Map objectives to individual and team KPIs
Taking objective-building to the next level and ensuring that each person on your team understands how their role will impact the overall objective is essential to putting a sensible tactical framework together. These team KPIs could include average response time, abandonment rate, first contact resolution (FCR), transfer rate, etc. - Map your team’s KPIs to the foundational processes in the customer service motion
With everyone aligned on the objectives and key results, it’s time to identify what needs to happen in order to bring these to life—channel inventory, required operational functionality (chatbots, virtual agents, automations, etc.), data management, agent training, new products and policies, etc. By identifying the processes that will help you achieve success, you’ll be able to line up the tools you need to succeed. - Map your processes and required functionality to a complementary set of tools that are simple, interoperable and efficient
Hint: your contact center platform should serve as the centerpiece of your stack as it relates to day-to-day execution. The stack should be unified by a central platform built to make the agent experience as efficient as possible so the customers can reach you, get help, and move on. Perhaps the most important part of this is the ability to easily build workflows that unify the native features with the integrated features. A good Contact Center platform will keep it all together.
We’ll be writing and sharing more of our thoughts on the modern Contact Center in the coming weeks. Feel free to bookmark our blog for best practices and updates in the customer service space.
You can also take a self-guided demo of our Contact Center platform, or request a custom demo from our team here.

How to Connect a Call to a Second Person the Low-Code Way Using PHLO
Plivo's SMS API and Voice API enables businesses to communicate with their customers at global scale. Sign up for free now.
Overview
Click-to-call enables your website users to engage with your support and sales teams on the website itself. Sometimes they want to speak to someone via their handset but initiate the call online or talk to someone directly from the website. You can implement this click-to-call use case using Plivo’s Browser SDK.
How it works
Prerequisites
To get started, you need a Plivo account — sign up with your work email address if you don’t have one already. You must have a voice-enabled Plivo phone number to receive incoming calls; you can rent numbers from the Numbers page of the Plivo console, or by using the Numbers API. Click-to-call requires JavaScript; we recommend using Node.js. If this is your first time triggering a PHLO with Node.js, follow our instructions to set up a Node.js development environment and a web server and safely expose that server to the internet.
Create a PHLO to handle call logic
To create a PHLO, visit the PHLO page of the Plivo console. If this is your first PHLO, the PHLO page will be empty.
- Click Create New PHLO.
- In the Choose your use case pop-up, click Build my own. The PHLO canvas will appear with the Start node.
Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming call, or API request.
- Click the Start node to open the Configuration tab, and then enter the information to retrieve from the HTTP Request payload — in this case key names are destinationNumber and phoneMeNumber. The values will remain blank as we will receive them when the request is made by the browser.
- Validate the configuration by clicking Validate. Do the same for each node as you go along.
- From the list of components on the left side, drag and drop the Initiate Call component onto the canvas. This adds an Initiate Call node onto the canvas. When a component is placed on the canvas it becomes a node.
- Draw a line to connect the Start node’s API Request trigger state to the Initiate Call node.
- In the Configuration tab of the Initiate Call node, give the node a name. To enter values for the From and To fields, enter two curly brackets to view all available variables, and choose the appropriate ones. The values for the numbers will be retrieved from the HTTP Request payload you defined in the Start node. Here From is 14159142884 and To is {{Start.http.params.phoneMeNumber}}.
- From the list of components on the left side, drag and drop the Call Forward component onto the canvas. Draw a line to connect the Answered trigger state of the Initiate Call node with the Call Forward node.
- Configure the Call Forward node to initiate call forward to another user. To enter values for the From and To fields, enter two curly brackets to view all available variables, and choose the appropriate ones. The values for the numbers will be retrieved from the HTTP Request payload you defined in the Start node. Here From is {{Start.http.params.phoneMeNumber}} and To is {{Start.http.params.destinationNumber}}.
- After you complete and validate the node configurations, give the PHLO a name by clicking in the upper left, then click Save.
- From the list of components on the left side, drag and drop the Call Forward component onto the canvas.
- Draw a line to connect the Start node’s Incoming call trigger state to the Call Forward node.
- In the Configuration tab of the Call Forward node, give the node a name. To enter values for the From and To fields, enter two curly brackets to view all available variables, and choose the appropriate ones. The values for the numbers will be retrieved from the HTTP Request payload you defined in the Start node. Here From is {{Start.http.params.header1}}. and To is {{Start.http.params.to}}.
- After you complete and validate the node configurations, give the PHLO a name by clicking in the upper left, then click Save.
Your complete PHLO should look like this:

Set up the demo application locally
Download and modify the code to trigger the PHLO.
- Clone the repository from GitHub.
- Change your working directory to click2call-webRTC.
- Install the necessary dependencies using the package.json file.
- Edit the .env file. Replace the auth placeholders with your authentication credentials from the Plivo console. Enter your PHLO ID, which you can find on the Plivo console.
- Edit /client/src/index.jsx and replace the caller_id placeholder with a Plivo number.
A review of the code
Let‘s walk through what the code does. The PHLO can be triggered either by an incoming call or an HTTP request.
Broswer SDK call
When someone clicks on an application button to initiate a call, we can use the Browser SDK‘s call() method to initiate a call from the application endpoint to the destination phone number. In this case our PHLO is the endpoint, so our outbound call is treated as an incoming call to our PHLO. When the request we make from the browser reaches the endpoint, the browser is connected to Plivo via the endpoint and the endpoint is attached to the PHLO, so when the browser makes a request to Plivo as an incoming call, Plivo connects to the endpoint, which in turn triggers the PHLO to forward the call to the destination number.
The code looks like this.
Here the extraHeaders is used to pass the caller_id for a call initiated by the broswer.
Click-to-call
Click-to-call is a more complicated use case because it requires us to actually send an HTTP request with a payload to the PHLO endpoint. Remember that we‘re making a call to our user‘s handset first, then connecting to the destination once the first call is answered. We need to get both phone numbers from the application and send them to the server. The code looks like this.
We need to listen for this request on the server. Once we receive the request and get the numbers from the payload, we set up another HTTP request that sends this data to the PHLO.
Assign the PHLO to a Plivo number
Once you’ve created and configured your PHLO, assign it to a Plivo number.
- On the Numbers page of the console, under Your Numbers, click the phone number you want to use for the PHLO.
- In the Number Configuration box, select PHLO from the Application Type drop-down.
- From the PHLO Name drop-down, select the PHLO you want to use with the phone number, then click Update Number.

Test
Run these commands.
You should see your basic server application running at http://localhost:8080/. Set up ngrok to expose your local server to the internet. Now make a call from your browser-based application to test it.
Note: If you’re using a Plivo Trial account, you can make calls only to phone numbers that have been verified with Plivo. You can verify (sandbox) a number by going to the console’s Phone Numbers Sandbox Numbers page.

How to Build a Voice Survey Application the Low-Code Way Using PHLO
Plivo's SMS API and Voice API enables businesses to communicate with their customers at global scale. Sign up for free now.
Plivo lets you automate voice surveys for use cases such as collecting feedback from customers and conducting polling on political issues. You can set up multiple levels of questions and walk users through different paths depending on the keys they press in response to your questions, and save the responses for analysis.
How it works

Prerequisites
To get started, you need a Plivo account — sign up with your work email address if you don’t have one already. If this is your first time triggering a PHLO with Node.js, follow our instructions to set up a Node.js development environment.
Create the PHLO
To create a PHLO, visit the PHLO page of the Plivo console. If this is your first PHLO, the PHLO page will be empty.
- Click Create New PHLO.
- In the Choose your use case pop-up, click Build my own. The PHLO canvas will appear with the Start node.
Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming call, or API request.
- Click the Start node to open the Configuration tab to the right of the canvas, then enter the information to retrieve from the HTTP Request payload. For this example, enter From and To phone numbers and your business name.
- Validate the configuration by clicking Validate. Every time you finish configuring a node, click Validate to check the syntax and save your changes.
- From the list of components on the left side, drag and drop the Initiate Call component onto the canvas. This adds an Initiate Call node onto the canvas. When a component is placed on the canvas it becomes a node.
- Draw a line to connect the Start node’s API Request trigger state to the Initiate Call node.
- In the Configuration tab of the Initiate Call node, rename the node to Call_Customer. You can rename nodes as you like to improve your PHLO’s readability. To enter values for the From and To fields, start typing two curly brackets. PHLO will display a list of all available variables; choose the appropriate ones. When you use variables in a PHLO, the values are retrieved from the HTTP Request payload you defined in the Start node.
- Next, drag and drop the IVR Menu component onto the canvas. Draw a line to connect the Initiate Call node‘s Answered trigger state to the IVR Menu node.
- Click the IVR Menu node to open its Configuration tab. Rename the IVR Menu node Question_1. For this example, select 1 and 2 as allowed choices. In the Speak Text box, enter a message to play to the user that introduces the survey and states the choices they can respond with. If you like, you can also configure the Language and Voice fields for the message.
- Repeat the process with another IVR Menu node. Rename it Question_2.
- To daisy-chain to the second question after the user gives a valid response to question 1, connect the Question_1 node‘s 1 and 2 trigger states to the Question_2 node.
- Configure the choices for Question_2 on its Configuration tab. Again, select 1 and 2 as allowed choices and enter a message to play to the user.
- Drag and drop the Play Audio component onto the canvas. Draw a line to connect the Question_2 node‘s 1 and 2 trigger states to the Play Audio node.
- In its Configuration tab, rename the node to Acknowledge_Participation. Enter a message of thanks to play to the user in the node‘s Speak Text box.
- Drag and drop the HTTP Request component onto the canvas. Draw a line to connect the Acknowledge_Participation node‘s Prompt Completed trigger state to the HTTP Request node.
- Rename the HTTP Request node Handle_Callback. Configure the node to post the survey results to a website. On its Configuration tab, enter key names answer1 and answer2. For their values, begin typing two curly brackets to view all available variables, then select Question_1.digits and Question_2.digits.
- Give the PHLO a name by clicking in the upper left, then click Save.
Your PHLO is now ready to test.
Trigger the PHLO
You integrate a PHLO into your application workflow by making an API request to trigger the PHLO with the required payload — the set of parameters you pass to the PHLO. You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through parameters when you trigger the PHLO from your application.
With a static payload
When you configure values when creating the PHLO, they act as a static payload.

Code
Create a file and paste the below code.
Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console.
With a dynamic payload
To use dynamic values for the parameters, use Liquid templating parameters when you create the PHLO and pass the values from your code to the PHLO when you trigger it.

Code
Create a file and paste the below code.
Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, +12025551234).
Test
Save the file and run it.
Note: If you’re using a Plivo Trial account, you can make calls only to phone numbers that have been verified with Plivo. You can verify (sandbox) a number by going to the console’s Phone Numbers > Sandbox Numbers page.

How to Build a Voice Alerts Application the Low-Code Way Using PHLO
Plivo's SMS API and Voice API enables businesses to communicate with their customers at global scale. Sign up for free now.
You can make voice API calls to alert customers to critical issues that require immediate attention. You can play recorded audio when the call recipient answers or use text-to-speech. You can then take action based on a dialpad key they press in response. You can set different actions if the call is not answered, if the line is busy, or if you reach voicemail.
Prerequisites
To get started, you need a Plivo account — sign up with your work email address if you don’t have one already. If this is your first time triggering a PHLO, follow our instructions to set up a development environment available in different languages.
Create the PHLO
To create a PHLO, visit the PHLO page of the Plivo console. If this is your first PHLO, the PHLO page will be empty.
- Click Create New PHLO.
- In the Choose your use case pop-up, click Build my own. The PHLO canvas will appear with the Start node.Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming call, or API request.
- Click the Start node to open the Configuration tab to the right of the canvas, then enter the information to retrieve from the HTTP Request payload — in this case, from and to numbers and a database server name.
- From the list of components on the left side, drag and drop the Initiate Call component onto the canvas. This adds an Initiate Call node onto the canvas. When a component is placed on the canvas it becomes a node.
- Draw a line to connect the Start node’s API Request trigger state to the Initiate Call node.
- In the Configuration tab of the Initiate Call node, give the node a meaningful name. To enter values for the From and To fields, start typing two curly brackets. PHLO will display a list of all available variables; choose the appropriate ones. When you use variables in a PHLO, the values are retrieved from the HTTP Request payload you defined in the Start node.
- Validate the configuration by clicking Validate. Every time you finish configuring a node, click Validate to check the syntax and save your changes.
- Next, create a node from the Play Audio component. Connect the Initiate Call node to the Play Audio node using the Answered trigger state.
- Click the IVR Menu node to open its Configuration tab. Rename the node to Gather_Input. You can rename nodes as you like to improve your PHLO’s readability. For this example, select 1 and 2 as the allowed choices, and enter a message to play to the user in the Speak Text field. If you like, you can also configure the Language and Voice fields for the message.
- Because we specified two allowed choices in the IVR menu, we need to drag and drop three Play Audio nodes onto the canvas — one for each option, plus one for invalid input. Rename the nodes Invalid_Input_Prompt, Resolved_Prompt, and Escalation_Prompt in their Configuration tabs, and enter appropriate messages in their Prompt fields.
- From the Gather_Input node, connect the Wrong Input trigger state to the Invalid_Input_Prompt node.
- From the Invalid_Input_Prompt node, connect the Prompt Completed trigger state back to the Gather_Input node. This sends the user back to the IVR menu if they press an incorrect option, or if they don‘t press any key.
- From the Gather_Input node, connect the 1 and 2 trigger states to the Resolved_Prompt and Escalation_Prompt nodes.
- Configure all three Play Audio nodes to each play a relevant message to the user. Audio playback can either be static or dynamic or a combination of the two; for example, you could specify in the Speak Text field “Your status is,” followed by a variable to include the dynamic text. You can bring up a list of available variables by typing two curly brackets in the Speak Text field.
- Drag and drop the Initiate Call component onto the canvas and rename the node to Escalation_Call.
- Draw a line to connect the Prompt Completed trigger state of the Escalation_Prompt node to the Escalation_Call node. This triggers a call to another phone number and announces the alert. You can set up any number of escalation numbers by creating similar nodes for each phone number.
- Draw a line to connect the Answered trigger state of the Escalation_Call node back to the Gather Input node. This will play the same prompt to the user after the original escalation call is answered and completed and give the user another chance to either resolve the call or escalate it.
- After you complete and validate all the node configurations, give the PHLO a name by clicking in the upper left, then click Save.
Your completed PHLO should look like this:

Your PHLO is now ready to test.
Trigger the PHLO
You integrate a PHLO into your application workflow by making an API request to trigger the PHLO with the required payload — the set of parameters you pass to the PHLO. You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through parameters when you trigger the PHLO from your application.
With a static payload
When you configure values when creating the PHLO, they act as a static payload.

Code
Create a file and paste the below code.
Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console.
With a dynamic payload
To use dynamic values for the parameters, use Liquid templating parameters when you create the PHLO and pass the values from your code to the PHLO when you trigger it.

Code
Create a file and paste the below code.
Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, +12025551234).
Test
Save the file and run it.
Note: If you’re using a Plivo Trial account, you can make calls only to phone numbers that have been verified with Plivo. You can verify (sandbox) a number by going to the console’s Phone Numbers > Sandbox Numbers page.
